Arrangement for providing a selectable expansion adapter on electronic device

ABSTRACT

An arrangement for providing a selectable expansion adapter on an electronic device is provided. In use, the adapter is inserted into and electrically coupled to the battery which is in turn inserted into a recess on the back of the device wherein the terminals of the adapter is coupled to connector of the battery and the battery together with the adapter are inserted into the recess with the connector coupled to circuit board of the device, thereby transmitting signals between the adapter and the device and storing data in the adapter. There is no sacrifice of precious space of the device with the additional memory of adapter added into. Hence, a slim electronic device is achievable. Further, there is no modification to the current construction of the device.

FIELD OF THE INVENTION

[0001] The present invention relates to the field of intelligent mobile phones and more particularly to an arrangement for providing a selectable expansion adapter on an electronic device such as intelligent mobile phone.

BACKGROUND OF THE INVENTION

[0002] Messages communication has become more rapid and frequent in this e-generation. Further, electronic devices particularly portable electronic devices have been widely used in various trades and in our daily life as an indispensable means. Moreover, nowadays more features are added in a portable electronic device such as intelligent mobile phone by manufacturer. For example, there is available an intelligent mobile phone equipped with a Global Positioning System (GPS) and a card storage means, a Motion Picture Coding Expert Group Audio Layer-3 (MP3), or a camera. Typically, a high-capacity memory for storing data is provided in such electronic device. Such expanded memory is typically in the form of expansion adapter. A security digital (SD) adapter is one of the most popular expansion adapters.

[0003] Conventionally, a unique SD recess is required to be provided on the electronic device for receiving SD adapter. Typically, there are two techniques for installing the SD adapter. One is to weld a SD adapter on circuit board of electronic device. It is disadvantageous because it results in a bulky electronic device. This, in turn, increases the weight of portable electronic device since SD adapter is secured to the electronic device and the SD recess. Such lack of adaptability really bothers user. The other is effected in the form of accessory in which SD recess is provided in an accessory releasably installed on electronic device so as to establish an electrical connection between input/output (I/O) ports of the SD recess and that of electronic device once connected. In use, user simply inserts SD adapter in SD recess on the accessory prior to inserting it in electronic device. It is disadvantageous because accessory with the inserted SD recess is a detachable device, resulting in an inconvenience to use. To the worse, accessory and electronic device are subject to damage due to frequent insertion and disassembly. Thus, it is desirable to provide a novel arrangement on an electronic device in order to overcome the above drawbacks of prior art.

SUMMARY OF THE INVENTION

[0004] It is therefore an object of the present invention to provide an arrangement for providing a selectable expansion adapter on an electronic device comprising a recess on the back of the electronic device having an opening; a circuit board in the electronic device having a plurality of terminals projected from the opening; and a battery shaped to be capable of inserting into the recess comprising a slot on one side for receiving a detachable expansion adapter having a plurality of terminals on one side and a connector extended from inside the slot to project on the surface of the battery; wherein in a use state the expansion adapter is inserted into the slot with the terminals of the expansion adapter coupled to the connector, and the battery together with the expansion adapter are inserted into the recess with the connector electrically coupled to the terminals of the circuit board, thereby transmitting signals between the expansion adapter and the electronic device and storing data in the expansion adapter. The advantageous benefits of the invention are as follows: There is no sacrifice of precious space There is no sacrifice of precious space of the device with the additional memory of adapter added into. Hence, a slim electronic device is achievable. Further, there is no modification to the current construction of the device. Furthermore, the device is adapted to both conventional battery and the battery of the invention. Thus it enables a user selection on the device.

[0005] The above and other objects, features and advantages of the present invention will become apparent from the following detailed description taken with the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS

[0007]FIG. 2 is a side view in part section of FIG. 1.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] Recently, more additional features are incorporated into portable electronic devices such as intelligent mobile phones. In response, a high-capacity memory for storing data related to the implementation of above feature is provided in such electronic device. Also, such expanded memory is typically in the form of expansion adapter. A security digital (SD) adapter is one of the most popular expansion adapters. Accordingly, the invention is aimed at providing a unique arrangement for providing a selectable expansion adapter on such an electronic device.

[0009] Referring to FIGS. 1 and 2, the configuration of the invention will now be described. As shown, electronic device 10 comprises a recess 11 on the back having an opening 111 and an internal circuit board 12 having a plurality of terminals 121 projected from the opening 111. A battery 20 is shaped to be capable of inserting into recess 11 and comprises a slot 201 on one side and a connector 21 extended from the bottom of slot 201 to project on the surface of battery 20. A SD adapter 30 has a plurality of terminals 301 projected on one side In use, insert SD adapter 30 into slot 201 with terminals 301 coupled to connector 21. Then insert battery 20 together with SD adapter 30 into recess 11 with the terminals of connector 21 electrically coupled to terminals 121 of circuit board 12. Note that, it is also possible of inserting a conventional battery into recess 11 when battery 20 of the invention is not required in a typical use of electronic device 10. Thus, the invention is highly adaptable. Moreover, connector 21 comprises a plurality of flexible pegs having one ends inserted into hole-shaped terminals 121 of circuit board 12 to be secured therein. Also, the other ends of the flexible pegs of connector 21 are biased by inserted SD adapter 30 to be secured to terminals 301. With such electrical connection between SD adapter 30 and circuit board 12, it is possible to transmit signals therebetween and store data in SD adapter 30.

[0010] In brief, in use SD adapter 30 is inserted into slot 201 of battery 20 which is in turn inserted into electronic device 10 with connector 21 coupled to circuit board 12. Hence, the advantageous benefits of the invention are as follows: There is no sacrifice of precious space of electronic device 10 with the additional memory of SD adapter 30 added into electronic device 10. Hence, a slim electronic device 10 is achievable. Further, there is no modification to the current construction of electronic device 10. Furthermore, electronic device 10 is adapted to both conventional battery and the battery 20 of the invention. Thus it enables a user selection on electronic device.
